Electronic horn S92E

Sound for greater safety: Signal horns are required in vehicles by law so that other road users can be made aware of dangerous situations in a clearly audible manner. The compact HELLA S92E horn is particularly suitable for commercial vehicles. It generates maximum attention with its high sound pressure level and is much more durable and problem-free than a conventional horn, as the vibration is generated electronically.

 

The S92E horn is powered by a battery current pulse. This is usually transmitted by a voltage pulse controlled by the steering wheel. This voltage pulse is fed to a relay to ensure voltage dip-free control current. A magnetic field is generated in the horn by the current, which attracts the metal core or shaft, causing vibrations of the steel diaphragm.

 

The HELLA S92E horn is available with a low (300 Hz) and a high (400 Hz) tone, each as a 12 V, 24 V, or multi-voltage variant, and produces a sound pressure level of approx.

112 dB(A) at 2 m distance. The multi-voltage variant is ideally suited for forklifts.
